BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mattress, and more particularly to aninflatable mattress that has a body and a coverlet tightly and flatlymounted detachably on the body without any wrinkles so that the coverleton the body looks tidy and would not be shifted inadvertently bypersons' movement on the inflatable mattress.

2. Description of Related Art

Inflatable mattresses are used generally in travels and camping becauseof their compressibility and portability.

However, people lying on the inflatable mattress feel less comfortablethan they feel when lying on a traditional bed because of no sufficientsoft cushion such as cotton fill put in the inflatable mattress.

U.S. Pat. No. 7,007,329 disclosed a conventional inflatable mattresswith a pillow top. The pillow top is mounted on a top of a mattressbody. However, the pillow top has no cushion function so that peoplelying on the pillow top on the mattress body would still feel moreuncomfortable as compared with conventional beds. Furthermore, theconventional inflatable mattress has a second fastener portion attachedto the edge weld of the inflatable mattress. The attachment prevents thepillow top to be secured tightly to the surface of the inflatablemattress and would appear to be “loose” across the surface of theinflatable mattress.

To overcome the shortcomings, the present invention provides aninflatable mattress with a coverlet to mitigate or obviate theaforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the invention is to provide an inflatable mattressthat has a body and a coverlet tightly and flatly mounted detachably onthe body without any wrinkles so that the coverlet on the body lookstidy and would not be shifted inadvertently by persons' movement on theinflatable mattress.

An inflatable mattress in accordance with the present inventioncomprises a body and a coverlet. The body is hollow, is inflatable andhas at least one first engaging member attached to the body. Thecoverlet is mounted detachably on and covers the body and has a topcushion and at least one second engaging member attached to the coverletand corresponding respectively to and detachably engaged respectivelywith the at least one first engaging member on the body.
